Show answer & explanation
Correct answer: D — Gametophyte
In Bryophytes (like mosses and liverworts), the gametophyte generation is the dominant and independent phase of the life cycle.
Q2. Which plant group evolved seeds that are not enclosed within a fruit wall?
Show answer & explanation
Correct answer: A — Gymnosperms
Gymnosperms are known as 'naked seed' plants because their seeds are not enclosed by an ovary wall (fruit).
Q3. The presence of seeds enclosed within a fruit wall is a characteristic feature of which major plant group among Algae, Bryophytes, Pteridophytes, and Gymnosperms?
Show answer & explanation
Correct answer: A — Gymnosperms
Gymnosperms are defined by the production of seeds, which are not enclosed within a fruit (as seen in Angiosperms). Pteridophytes and Bryophytes do not bear seeds.
Q4. Which group of plants exhibits the first appearance of true vascular tissues (xylem and phloem) in their stems and leaves?
Show answer & explanation
Correct answer: D — Pteridophytes
Pteridophytes (ferns and allies) are the first group of land plants to develop true vascular tissues, which allows for greater height and structural support.
Q5. In Bryophytes, the dominant plant body is typically characterized by which structure?
Show answer & explanation
Correct answer: C — Thallus
Bryophytes (mosses, liverworts) are non-vascular plants. Their dominant plant body, called the thallus, is undifferentiated and lacks true roots, stems, and leaves.
Q6. What is the fundamental difference between the mode of dispersal in Pteridophytes and Gymnosperms?
Show answer & explanation
Correct answer: D — Pteridophytes disperse via spores, Gymnosperms disperse via seeds.
Pteridophytes reproduce using spores, while Gymnosperms reproduce by bearing seeds. This is a core difference in their reproductive strategies.
Q7. Which group of plants is considered the first group to exhibit true vascular tissues (xylem and phloem)?
Show answer & explanation
Correct answer: B — Pteridophytes
Pteridophytes (ferns and their relatives) are the first group of land plants to develop true xylem and phloem, enabling efficient water transport.
Q8. Which group of plants lacks true vascular tissues (xylem and phloem)?
Show answer & explanation
Correct answer: A — Bryophytes
Bryophytes (mosses, liverworts) are non-vascular plants and therefore lack specialized conducting tissues like xylem and phloem.
Q9. Which of the following groups of plants is considered the first group that developed vascular tissue?
Show answer & explanation
Correct answer: C — Pteridophytes
Pteridophytes (like ferns) represent the evolutionary step where vascular tissues (xylem and phloem) evolved, enabling taller growth.
Q10. Which group of plants is characterized by the presence of true vascular tissues (xylem and phloem)?
Show answer & explanation
Correct answer: A — Pteridophytes
Pteridophytes (ferns and their allies) are the first group of land plants to exhibit true vascular tissues, which allows for efficient transport of water and minerals, distinguishing them from non-vascular plants like Algae and Bryophytes.
Q11. Gymnosperms are distinguished from Pteridophytes primarily by the presence of seeds. What is the major difference in their reproductive structures compared to Pteridophytes?
Show answer & explanation
Correct answer: D — Gymnosperms produce seeds
The defining characteristic that separates Gymnosperms from Pteridophytes is the production of seeds (naked seeds), whereas Pteridophytes reproduce via spores.
Q12. Gymnosperms are commonly known as 'naked seed plants'. What distinguishes them from Angiosperms?
Show answer & explanation
Correct answer: A — They possess seeds that are not enclosed within a fruit
Gymnosperms produce 'naked seeds' (not enclosed within a fruit ovary), distinguishing them from Angiosperms (flowering plants).
Q13. Algae are primarily characterized by which mode of nutrition?
Show answer & explanation
Correct answer: C — Autotrophic (photosynthetic)
Algae are photosynthetic organisms, deriving their food energy through photosynthesis.
